I noticed a strange feature - sometimes the system completely freezes. CPU Usage shows 99-100% utilization of all 4 laptop cores. There is no open source program that can do this. The task manager shows that so many resources are being eaten up by the sidebar of gadgets, but when the panel is closed, the pandemonium continues. It just came and goes the same way. A consultation with a friend showed that he himself had the same problem with cries of "I thought that my computer was sometimes so stupid."
Who faced similar problems?

Windows 7 is installed on four machines, I have never seen anything like it anywhere

Maybe iron problems? For example, I had this when the hard drive was covered.
As an option, enable "display processes of all users" and cut down slow processes, and then try to find a common one :-)

I didn’t see this in the seven, but in XP the disk indexing service did something similar (help in quickly finding files). After disabling the service, this XP behavior stopped.

Try to remove the gadget bar from autorun. Do not close after freezing, but generally remove it so that it does not even load. Will the problem reoccur?

I periodically load the processor up to 100% with the "Universal PNP Device Host" service. Try turning it off. But ... without it, when I try to get to the local DC hub, I get a message that the address does not belong to the Beeline local network. So I just restart it periodically if it loads the processor.

Disable the antivirus and look at the result.

Most likely a problem with the driver (Antiviruses and Firewalls especially like to do this after the update, well, hardware drivers), in such cases it is easier to reinstall the system than to look for something that is buggy. If after reinstalling the problem returns immediately, then the problem is in the hardware, if not immediately, see what you set before that.

There was a similar problem in Win7. Process Explorer indicated that the percent loads "Interrupts". If so, then google for that word.
